Abstract (en)
A ceramic honeycomb structure includes a number of quadrilateral cells (1) arranged adjacent to each other. To increase strength of the structure triangular cells (4) are arranged in the proximity of the outer circumference of the honeycomb structure. Partitions (3) of the triangular cells are oblique to partitions (2) of the quadrilateral cells (1) and extend substantially towards a center of the honeycomb structure. The oblique partitions (3) of the triangular cells serve not only to improve the isostatic strength of the honeycomb structure but also to avoid high pressure losses.
